An improved strategy for building brackishwater culture ponds with iron pyrite soils in mangrove swamps
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The problems associated with acid sulfate soil limit the potential utilization of vast coastal areas of mangrove swamps for brackishwater aquaculture. There is an estimated 4.8 million ha of mangrove area in the ASEAN ...
The effects of stocking densities on growth and survival of Penaeus vannamei in cow manure-enriched ponds
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Ecuadorian Penaeus vannamei were stocked in eight dirt ponds (approximately 163 m2) at four different types of density, i.e., 5 shrimp/m2, 10 shrimp/m2, 15 shrimp/m2, and 20 shrimp/m2. The initial body weight ranged between ...
Brackishwater shrimp culture in India and its impact on socio-economics
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Utilization of potential area for shrimp culture in the traditional system was very meager — just 1.8% of total estimated available area of 1.45 million ha. The traditional paddy and fish culture and paddy cum fish culture ...
The integrated use of artemia in shrimp farming
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The use of freshly hatched Artemia nauplii in penaeid hatcheries is a common practice, although a broader application of Artemia in shrimp farming is gaining more and more interest. In this regard, an integrated use of ...
The effects of manures and pelleted feeds on survival, growth and yield of Penaeus stylirostris and Penaeus vannamei in Panama
(Aquaculture Department, Southeast Asian Fisheries, Development Center, 1985)
Brackishwater ponds (0.8 m deep and 600 m2) on the Pacific Coast of Panama were stocked at 5/m2 with post-larval shrimp (1 cm, 0.05 g) collected from the wild. Species composition at stocking was 56% Penaeus vannamei, 33% ...
Genetic changes during development of penaeid shrimp
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
As penaeid shrimp grow from the earliest naupliar stages, through protozoeal and mysis stages, to postlarvae, they develop greater morphological and behavioral resemblance to the adults. Electrophoretic analysis of cytoplasmic ...
Studies on the artificial insemination and fertilization of grass shrimp, Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The culture of grass shrimp, Penaeus monodon has become a fast-growing enterprise in Taiwan since formulated shrimp feed was successfully developed in 1978. In 1983, the total postlarval production for stocking reached 600 ...
Osmotic, total protein and chloride regulation in Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The osmotic, total protein and chloride ion regulation in two size groups (10 and 30 g) of Penaeus monodon Fabricius was investigated. Preliminary experiments showed that osmolality, total protein and chloride concentrations ...
Nutritional value of marine yeast fed to larvae of Penaeus monodon in combination with algae
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
Saccharomyces cerevasiae and Rhodotorula aurantica, two marine yeast species, were fed to Penaeus monodon larvae (N6 to M1) singly and in combination with Tetraselmis sp. and Chaetoceros calcitrans in varying proportions. ...
Floating cage nursery culture system for Penaeus monodon
(Aquaculture Department, Southeast Asian Fisheries Development Center, 1985)
The use of floating cages as nursery for Penaeus monodon postlarvae was tried at the Batan, Aklan Substation of the SEAFDEC Aquaculture Department. The cages were made of bamboo and measured 2 × 5 × 1.5 m (effective volume ...
